Crossing the straight of Gibraltar

Crossing the straight of Gibraltar

From Cascais, in Portugal, our plan was to move through the straight of Gibraltar, and find a nice spot on the costa Blanca. I have crossed shipping channels many times, even in dense fog, using the radar, so how hard could it be?

Our first leg, from Cascais to Cabo Sao Vicente went at a brisk pace of 7 knots, running on just the genoa. Hint, if the mainsail is not up, you don't have the risk of it accidentally gibing, and we were happy with our seven knots. On our way to Cabo de São Vicente, we didn't see that many ships, and this is generally how we like it. We did expect this situation to change, however, in the near future.

The leg from Cabo de São Vicente to the straigt of Gibraltar, was quite pleasant, the weather turned into very sunny and very warm, and the wave height reduced from nearly 3 meters,to less than a meter. We though we were already in the Med. Elizabeth made a wonderfull vegetarian meat loaf (I know, it sounds a bit like a contradiction, but wait until you had the first bite!) and a salad.

Also, on several occasions, we were greeted by a large groups of curious dolphins. Although we could see many ships on the AIS display, all heading towards or from the straight, we did actually see surprisingly very few vessels, mainly due to the fact we were staying out of the way of the main shipping channel. We used all our sails, including a first reef, on this section of the trip, as the wind slowly reduced on out way to Gibraltar, no next to nothing (we had to use the iron mainsail), picked up again to 20 knots, and just before Tarifa, dropped again to nothing, and finally settled into a refreshing 30 knots... In the wrong direction. The kite surfers at Tarifa must have been happy. We on the other hand were battling the 30 knots over the deck, wind against current and the lovely effect this has on the waves, and reduced visibility.

We did not get to see the kitesurfers, unfortunately, do to the heavy fog, which descended upon us throughout the night. We had actually planned our trip, so we would cross the Gibraltar straight in daylight, to make the crossing easier. However, this was not meant to be... Using the radar, and AIS, it was very easy to establish the viability range. In the worst part, the visibility was just a few hundred meters, causing me to see a Moroccan vessel, only at the last moment, as it did not have AIS or radar reflector. Presumably the vessel was engaged in nefarious activities, either smuggling or possbily worse,  illegally fishing in Spanish waters, because we saw it in the Spanish waters, and it was crossing the shipping channel towards morocco.

When we passed in front of the tower of Tarifa, we could barely see it, at a range of less than 2 nautical miles. At this distance, suddenly a high speed catamaran appeared on our AIS display. It was heading right for us at 22 knots! Evasive maneuvers... We did see a second high speed catamaran, coming out of Gibraltar.

When we crossed Gibraltar, we could barely make out the rock, on account of the viability being much better at higher altitudes. However, as soon as we made out way into the Med, the wind dropped to nearly nothing, the fog lifted and the sun came out. All good things come togather, as by this time, Elizabeth's samosas came hot out of the oven.

We decided to set sail to Estepone for a thorough decrustification.

Debris everywhere...

As I am typing this, the nearest land is 94 Nautical miles away. But wait, what is this huge piece of fish net doing here floating arouind? And Hey, what is that plastic bag doing there floating around? And mhh, that definitely looks like a tube of toothpaste or the likes floating out there. It is unbeleable that we humans have such a big impact on the environment, even so far offshore. The dolpins give us a decent sent off, and what do we sent? Plastic waste, and lot's of it. Time to do some research on this... DNews has a good youtube video on this. Also Plasticbank.org has good information. Apparently plastic waste into oceans is a massive problem. How does it get there? Waste from passing ships (mainly big ones) and waste that enters from the land, either wind blown, or via sewages and overflows. A piece of plastic that enters the sea will float around for 1000 years, photo degrading in ever smaler particles. That is, if it is not snagging up a turtle, or get stuck in the stomach of some animal or such like. 



Most of the plastic ends up in large plastic “islands” called gyers.



 Because the ocean rotates around these points the plastic waste ends up floating around there. There are 5 such gyres around in the world. There is even a charity organization called “Five gyres” that raised awareness of the issue, conducts research to document the extend of the problem, and lobbies to get laws implemented to reduce plastic waste. What can I do you ask? Consider:
  1. Minimize plastic consumption, and if you use it, ensure it is properly disposed off.
  2. Donate to “Five Gyres”,
  3. Pick up five pieces of plastic every time you are outside,
  4. Make others aware of the issue
  5. make sure that any sanity products you buy do not contain plastic micro beads, that are DESIGNED TO FLUSH INTO THE OCEAN! And in doing so, end up in fish, and back onto our dinner plates
